I just pulled the engine oil dipstick on my new 2800 HST. First off, it looks nothing like the dipstick shown in the operators manual. It has a small hole in the dipstick about 1/4" from the bottom of the stick. Then, there is another hole further up about 2 1/2" from the bottom of the dipstick. My oil level is about 1" above that top hole - about 3 1/2" to 3 3/4" from the bottom of the dipstick. How do I know where the oil level is supposed to be at? There is atleast 2" between the two holes and no other markings. Is it overfilled, and if so, could this have hurt anything?
